Product details

This eliminates the quartz cold-start frequency drift and reduces sensitivity to board-level vibration — the MEMS die is bonded directly to the package substrate, so the oscillator starts at its rated frequency without the warm-up transient typical of quartz.

100 MHz LVDS — signal integrity and load budgeting

LVDS output at 100 MHz delivers a differential swing of roughly 350 mV into a 100-Ω termination — the low swing reduces EMI and keeps the edge rate controlled for point-to-point clock distribution on a 4-layer or 6-layer PCB.

Package and supply — board-fit checklist

6-SMD no-lead package, 3.20 mm × 2.50 mm body, 0.90 mm seated height. The 2.25 V to 3.63 V supply range covers 2.5 V and 3.3 V rails without an external regulator — the internal LDO regulates the MEMS core from the input rail.

Frequently asked questions

Can the DSC1123CI5-100.0000T replace a quartz oscillator in an existing design?

Yes, if the existing quartz XO is a 100 MHz LVDS output in a 6-SMD footprint with a 2.25 V to 3.63 V supply. The MEMS base resonator eliminates the quartz warm-up drift and is less sensitive to vibration, but the pinout and output type must match — confirm the existing oscillator's function pin (enable/disable) assignment against the DSC1123 datasheet before committing.
